Arsenal have been successful in their appeal to overturn the red card shown to Mohamed Elneny during Sunday's 3-2 Premier League win over Southampton.
The midfielder was dismissed by referee Andre Marriner for violent conduct after raising his hands to Saints full-back Cedric in stoppage time at Emirates Stadium.
Elneny, who signed a new long-term contract last month, was facing a three-match ban, which would have ruled him out of games against Newcastle United, West Ham and Manchester United.
But on Tuesday, the Football Association released a statement declaring that "an Independent Regulatory Commission accepted that he was wrongly dismissed for violent conduct".
In a fiery end to the game, Southampton's Jack Stephens was also sent off for tangling with Jack Wilshere.
Arsenal next face CSKA Moscow on Thursday with a healthy 4-1 lead from the first leg, while Newcastle United lie in wait on Sunday.
